Compare two points and see if they're the same, using a threshold.
Whether points are the same within a threshold. Uses fast distance approximation (linear per-component distance).
static bool PointsAreSame ( const [TVector](API\Runtime\Core\Math\TVector)< T > & P, const [TVector](API\Runtime\Core\Math\TVector)< T > & Q )
